The GPS III’s Highway Page also provides graphic steering guidance to a destina-
tion waypoint. As you head toward your destination, the middle of the screen pro-
vides visual guidance to your waypoint on a moving graphic “highway.” Your present
position is at the bottom center of the highway display. The line down the middle of
the highway represents your desired course. As you navigate toward a waypoint, the
highway will actually move—indicating the direction you’re off course. To stay on
course, simply move toward the center of the highway.
The top of the page indicates speed and distance to your destination (or the next
waypoint in a route), along with a track compass showing current direction of
travel. Directly below the distance reading is the time required to reach your desti-
nation (or the next waypoint in a route), in hours/minutes or minutes/seconds. The
pointer at the bottom of the page also shows the bearing to your destination, relative
to your current track. If the pointer points straight ahead, you’re heading directly to
your destination!
Use the Highway Page as your primary navigation page (in lieu of the Compass
Page) when your main concern is following a defined course.
If you move off course the
highway display will move,
indicating the direction you
are off course. To stay on
course, simply move toward
the center of the highway.
As you approach your desti-
nation, the graphic highway
will stop at the destination
waypoint. You have arrived
when the waypoint is at the
bottom center of the display.
